...one of the earliest surviving examples of a television sitcom (though some prefer to consider it a drama/comedy).
The first television sitcom was "Pinwright's Progress" on the BBC (1946-1947), of which nothing survives. Also lost is "The Laytons", a 1948 DuMont sitcom that was the first to feature an African-American in a regular supporting role.
A total of six 1949-era episodes of "The Goldbergs" survive, 5 of which are on the Internet Archive.
Also surviving from 1949 (in terms of TV sitcoms) are an episode of "Mary Kay and Johnny" (NBC-TV, though it's possible other episodes exist), an episode of the short-lived television-version of "Easy Aces" (DuMont-TV), a few episodes of "Growing Paynes" (DuMont-TV) and not much else. None of these are on the Internet Archive. Some 1949-era episodes of "The Life of Riley" are on the Internet Archive, but they heavily edited syndication prints with a laugh-track that wasn't present during the orignal broadcast.
"The Goldbergs", thankfully, is devoid of a laugh-track. Indeed, they weren't even used on a sitcom until early 1950 (see: "The Hank McCune Show", which was the first TV sitcom to use one). But "The Goldbergs" never used one even later on. This makes it special, though not unqiue, among 1950s comedies. See also: "The Trouble with Father" (most episodes), "Mama", and "Beulah" for more 1950s comedy without a laugh-track.
I realise this is more of a comment than a review, but I thought you people might find the above info to be interesting.
